The aim of the study – To determine and assess the variability of movements during the vertical standing jumps with and without the regressive information. Subjects: The subjects were healthy men who cultivate triathlon (age 19-20 years; n = 10). The objectives: to identify and evaluate the variability of vertical jumps when the jumps are performed at 50% of maximal intensity without using the backward information; to identify and evaluate the variability of vertical jumps when the jumps are performed at 50% of maximum with the regressive information about the accuracy of jump; to identify and evaluate the variability of vertical jumps when the jumps are performed at 30% of maximum (before and after the workload) and at maximal intensity (workload) without the use of regressive information; to evaluate the variability of vertical jumps when the jumps are performed at 30% of maximum (before and after the workload) and at maximal intensity (workload) with the backward information for the control jumps. The main conclusions of the study are the following: During the vertical jumps at 50 % of maximum, we have determined similar repetition of vertical jump. This similarity of vertical jumps’ accuracy was determined during the jumps before the workload, during the workload, and after the workload; The repetition of the similar vertical jump depended on the delivery of regressive information: first two jumps with the backward information were significantly increased in comparison to...

The aim of this study is to determine the effect of regular and long term sports games and cyclical sports events exercises at the age of 11–14 for boys development in motor and sensomotor abilities and cardiovascular system adaptation peculiarities. The next methods were used: Tapping test, Roufier exercise test, vertical jump test, 30 s maximal jumping test, measurements of arterial blood pressure, electrocardiography (ECG), dynamometry, stabilography, measurements of body mass components, non linear ECG data analysis methods. Conclusions: 1. Motor and sensomotor abilities of non-athlete children develop in the age phase of 11–14: muscles’ power and capability, central nervous system (CNS) efficiency indices increase. The improvement of results is irregular: the rate of improvement decreases at the age of 13–14. 2. The increase in motor, sensomotor and cardiovascular system indices of cyclic sports events for children were indicated higher than in non-athlete contemporaries at the age of 11–13. Statistically significant differences of cardiovascular and most of CNS indices were not noticed at the age of 13–14 and muscles’ functional preparedness indices were significantly better than non-athletes. 3. The improvement of children, attending sports games trainings, functional preparedness indices are significantly greater than in non-athletes and cyclic sports events athletes at the age of 11–13. At the age of 13–14 the rate of indices reduce and except muscles preparedness... [to full text]

The purpose of the study was to estimate the functional state of the central nervous system of the children with spastic hemiplegia in physiotherapy and functional training. The subjects were 18 children with spastic hemiplegia and 32 nondisabled pupils, age 8-13 years old. In our study we used following methods – romberg test, electronic balance board, tapping test, mathematic statistics. The obtained results showed that the evaluations of the balance of the children with spastic hemiplegia were significantly better in sagittal plane than frontal. The functional state of central nervous system of the children with spastic hemiplegia and nondisabled pupils showed high changes in freqeuncy of movements during tapping test. The used physiotherapy improved the functional state of the central nervous system of the children with spastic hemiplegia. The functional training programm were more effective than the used physiotherapy programm.
